Given numbers are 215, 561, 110, 324

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 561 are 3 x 11 x 17

Prime factors of 110 are 2 x 5 x 11

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 215, 561, 110, 324

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(215, 561) = 120615

GCD(215, 561) = ( 215 x 561 ) / 120615

= 215 / 561

= 215

Step2:

LCM(1, 110) = 110

GCD(1, 110) = ( 1 x 110 ) / 110

= 1 / 110

= 1

Step3:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

So, Greatest Common Divisor of 215, 561, 110, 324 is 1
